Answer:
It should be <u>35.4</u>
Step-by-step explanation
Because 35 degrees makes a right triangle
The coefficient in (4x-2) is the -2
Answer:

Step-by-step explanation:
In order to find r we have to square both sides of the equation

The *square root* sign cancels out the *squared* sign therefore:

Answer:
-14
Step-by-step explanation:
Okay first we must simplify the expression.
so this:(3x^2 + x-2)(x - 5)
becomes this:3x^3-14x^2-7x+10
then we look at the coefficient of x^2 and we see that it's -14
